The biggest problem is the main sheet attachment. We've broken two of them becsause of over enthusiatic crew on the mainsheet button
My solution :
1. make an aluminium piece of the same thickness but a bit longer and WELD it to the boom.
2. trip the cct breaker for the main sheet winch so it MUST be wound in manually.
